Hello there, @usercompliance.

You can export reports and lists from your QuickBooks Online account. This way, you can use it in migrating it. I can guide you in doing so.

1. Go to the Gear icon ⚙.
2. Choose Export Data.
3. On the Reports tab, set the date range.
4. Add or remove items from the Reports and Lists tabs by toggling the slider.
5. Select Export to Excel.

You can also download non-posting transactions and attachments such as invoices, receipts, bills, etc. balances. You can refer to this article for the more detailed steps: Export reports, lists, and other data from QuickBooks Online.
